APPARATUS FOR HANDLING ASHES AND OTHER MATERIALS.

To all whom it may concern:

Be it known that I, WILLIAM of Pittsburg, Allegheny count vania, have invented a new and paratus for Handling Ashes and other Materials, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which the W. DARLEY, Pennsyluseful Apaway, of one form my invention.

My invention has relation to apparatus for handling ashes or other material of like character, and has been more particularly designed for use in the removal of ashes from the boilers of manufacturing plants, otlice buildings and other places where ashes are produced in considerable quantities.

My invention further relates to apparatus of this class, in which the ashes are drawn rom the ash pits of furnaces by hopper from which they may be discharged directly into a car or wagon, or from which they may be forced pressure as described of apparatus embodying and claimec in m finding application Serial N 0. 408,511, filed ecember 30th, 19 7.

My present invention is designed to provide means for effecting a complete separation of the ashes and air in the hopper of the receptacle into which the ashes are drawn by suction.

e precise nature of my invention will be best understood by reference to the ac companying drawings, in which I have shown one embodiment thereof, it being premised, however, that various changes may by those skilled in the art without departing from the spirit and scope of my invention as defined in the appended claims.

In this drawing, the numeral 2 designates the receptacle into which the ashes are drawn through the pipe 3, which leads to the ash pit or other point from which the ashes are to be removed.

4 designates a pipe of larger cross-sec tional area than the pipe 3, and which is connected to a fan (not shown) arranged I receptacle 2, whereby the ashes will be drawn therein through the pipe 3. The vessel 2 has'a contracted lower portion 2 terminating in a dischar e throat, 2 which may be arranged to -(llS- Specification of Letters Patent. Application filed July 17, 1908. Serial No.

charge directly into a wagon or other receptacle, or to w ich a discharge pipe leading to another point may be connected, as described in my Thesuction the upper portion of the vessel 2, has an en larged portion 5 which extends downwardly within the upper portion of the receptacle 2, its lower open end preferably terminating at. the normal water level of a water pan (3, which is suitably supported within the upper portion of the vessel 2, and which is supplied with water by an inlet pipe 7. The baflies 5" and 5 are so arranged that 5 has its lower portion projecting into the water in the pan 6, while 5 preferably has its lower end at the Water level. The spray pipe 7 which is supplied by the water pipe positioned to propel a constant spray of water down the outer face of the battles 5 The pan 6 preferably has bottom 8 with a discharge opening 9 at its lower side, which is connected by an outlet pipe 10 with a sediment tank 11. This sediment tank has an outlet pipe 12 extending upwardly-to about the normal ,water level of the pan 6, where it charge pipe 13.

14 is a supplemental discharge pipe leading outwardly from the upper portion of the water tank, and also connected to the discharge pipe 13 with a trap bend 15 therein, the purpose of this supplemental outlet being to provide for the overflow of the pan Girl the event that the pipes 10 and 12 or either of them, should become clogged up. The sediment tank 11 is provided with the dischargebell 16, or with any other suitable means, by means of which it may be emptied and cleaned when desired.

said application.

17 designates a suitable scraper, whose actuating rod extends outwardly "through the stufling boxes 18, in the walls of the water tank 6 and of the receptacle 2, and which may be drawn back and forth on the inclined bottom of the water pan for the purpose of cleaning it. v

19 designates a valve for controlling the connection between the pipe 4 and the interior of the receptacle, and which may be operated by a rack and pinion movement 20, or by any other suitable means.

21 is a water pipe which is arranged to discharge into-the pipe 3 preferably near where the latter pipe discharges within the receptacle 2. find it a great advantage pipe 4, which is connected to an inclined is connected to a disto wet the ashes in this manner before they are discharged into the receptacle, since n this way they can be thoroughly wet to the necessary extent with a rninnnum of water and the presence of dust in the receptacle is avoided. I

The water pan 6 is or considerably smaller diameter than the interior diameter of the upper portion of the receptacle Else as to leave a surrounding air chamber, its will be seen the air which is exhausted from the receptacle 2, will pass upwardly around the Water receptacle, and is forced to pass through the water pan, around the ballles and through the Water in pan 6 in order to enter the pipe .1, as indicated by the arrows. The Water will therefore remove from the air all dust and ashes which might otherwise be carried oft with the exhaust to the fan. It is the provision of this water pan ar ranged in the manner described which enables me in most cases to dispense with the water pipe 21, which has heretofore been necessary to prevent dust and ashes being carried over the fan, and which necessitates the constant mixture of water with the ashes as they are discharged, or previous to their discharge.

1 do not limit myself to the exact arrangement of the parts which it have shown and described, it being obvious that vapious changes may he made in detail thereof without departing from my invention. Thus, the receptacle 2 may be oi an desired character; the water pan may be differently conslructed, and the sediment tank can be in some cases omitted.

What I claim is l. in apparatus of the character descrihc il, a receptacle, an inlet pipe leading therein to convey the material to the re ceptacle, an exhaust pipe connected to the receptacle, a water pan supported. in the reccptaclc above the inlet pipe, baiiling plates surrounding the mouth of the exhaust pipe and within the outer wall of the water pan, and means for maintaining a normal level of water in said pan; substantially as described.
